Why HP Tuners for US cars?

American cars (GM, Ford, Dodge/RAM, Jeep, Chevrolet, Cadillac, Buick, etc.) differ in their drivers, strategies, and security features. HP Tuners provides:

  • Deep diagnostics (VCM Scanner): live logs, hundreds of parameters, active tests, quick fault analysis.

  • Calibration control (VCM Editor): access to key fuel, ignition, torque, boost and gearbox maps.

  • Full documentation support : PID sheets, mask descriptions, calibration guides and technical notes – we do not rely on “ready-made” solutions.

  • Secure workflow : backups, calibration comparisons, change validation, logging of each step.

What do you actually gain as a customer?

  • Better throttle response and flexibility – the car drives "downhill", without empty zones.

  • Stable, repeatable power – no AFR jerking or "floating".

  • Lower EGT/oil temperatures during dynamic driving (correct mixture and ignition).

  • Smoother, stronger gear changes (AT/TCU): optimisation of points, pressures, lock-up times.

  • Fuel adaptation (E10/E15, 95/98/100, Flex Fuel where it makes sense).

  • Disabling troublesome functions (where legal and safe): e.g. DOD/AFM in V8, start-stop, speed limiter (tor), VATS after SWAP, etc.

  • Full documentation with measurements – logs, graphs, description of changes, service recommendations.

Scope of work (examples)

Engine (ECU)

  • Calibration of fuel/ignition, torque maps, lambda and knock control.

  • MAF/MAP scaling, intake/exhaust corrections, turbo wastegate/boost control.

  • Flex Fuel / stoichiometry / cold start / idle / decel.

  • DOD/AFM/MDS – deactivation.

  • Speed ​​limiter, rev limiter, pedal mapping.

Transmission (TCU) – AT/6L80, 8HP, 10R80 etc.

  • Gear shift points for real engine torque.

  • Pressure, line pressure, lock-up, kickdown, launch strategy.

  • Reduction of jerks, shorter gear shift times, less lag.

Diagnostics and preparation

  • Full VCM Scanner logs (with sensible PIDs), active tests, health-check.

  • Error analysis, fuel system, ignition, air flow control.

  • Verification of mechanical mods (intake, exhaust, turbo, converter).

Our Process (No Bullshit)

  1. Interview and purpose – what are we focusing on: off-road, comfort, track, city/highway, trailer towing?

  2. Logs + diagnostics – we detect real limitations (fuel, ignition, EGT, TCU slip).

  3. Baseline on the dyno – starting state (power/torque, AFR, IAT/ECT/EGT*).

  4. Calibration with HP Tuners – edit → logs → verify.

  5. Road test – various driving profiles (city, highway, load).

  6. Final on the dynamometer – result + documentation package and recommendations.

HP Tuners Innovations That Make a Difference

  • MPVI3 + Pro Feature Set/Pro Link+ – fast read/write, stable communication, analog logs (e.g. broadband).

  • Extensive ECU/TCU support for US brands and constant definition updates.

  • Compare/History – safe iterations and full reproducibility of changes.

  • Documentation and community dev – real descriptions of masks, not "legends from forums".

Who does this make sense to?

  • V8/V6 from the USA (Hemi, LT, LS, Coyote, Pentastar, Ecoboost etc.) – stock and modified.

  • Pickup/SUV for towing – mid-range torque, temperature control.

  • SWAP/retrofit – legal project launch with proper calibration.

  • Track/drag racing – predictable response and stability of parameters under load.

How much is it?

  • From PLN 1,800 gross – range depends on model, ECU/TCU, HP Tuners license/credits status, mechanical modifications and required iterations.

  • We will prepare an accurate quote after a short interview and review of the controller/logs.

FAQ (short and to the point)

What does the valuation depend on?
Depending on the ECU, HPtuners credits are our responsibility. They depend on the complexity of the project and the engine generation.

Does changing the map void the warranty?
Maybe. We inform you about the risks before takeoff.

Does it have to be a dyno?
We recommend it. It gives us a baseline and repeatability.

Will you only make the transmission (TCU)?
Yes, as long as the TCU is supported and the engine parameters are consistent.

Are you deactivating DOD/AFM/MDS?
Yes
